github grafana/agent v0.7.2

This is release v0.7.2 of the Grafana Cloud Agent!

Notable changes:

Despite being a patch version bump, there are some important additions to this release!

The biggest change is the enhancements to host filtering mode: host_filtering mode now supports Docker Swarm and Consul targets out of the box. A meta-label __host__ can now be used for filtering targets. __host__ can be combined with the new host-filtering-specific relabeling rules configured by host_filter_relabel_configs. Relabeling rules used for host filtering are temporary and are just used for the filtering process, so only use it for creating the __host__ label. For detailed information, check out the documentation on host filtering in the Operation Guide.

v0.7.0 had a bug where the docs made note of a push_config field for configuring Tempo but the Agent actually expected a field called remote_write. This has now been fixed and push_config will work as expected.

Internal dependencies have had their versions bumped:

  • The internal version of Prometheus used is now 2.21
  • The internal version of opentelemetry-collector used for tempo is now 0.13.0
  • The internal version of promtail used for Loki is now 2.0

Installation:

Grafana Cloud Agent is currently distributed in plain binary form, Docker
container images, and a Kubernetes install script. Choose whichever fits your
use-case best.

Kubernetes Install Script

The following scripts will download and install two Kubernetes manifests for the
Agent. The first manifest collects metrics, the second collects logs, and the
final collects traces. You will be prompted for input for each manifest. The
script requires curl and envsubst (GNU gettext).

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/grafana/agent/v0.7.2/production/kubernetes/install.sh)" | kubectl -ndefault apply -f -
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/grafana/agent/v0.7.2/production/kubernetes/install-loki.sh)" | kubectl -ndefault apply -f -
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/grafana/agent/v0.7.2/production/kubernetes/install-tempo.sh)" | kubectl -ndefault apply -f -

Docker container:

docker pull "grafana/agent:v0.7.2"
